Title: Power source voltage-controlled amplifier
Inventor: AMADA NOBUTAKA
IPC: H03F1/02
Filed: 1982-01-19
Abstract: PURPOSE:To prevent a breakdown of a transistor (TR) due to the magnetic saturation of a high frequency transformer by holding the maximum of the duty ratio of a control signal applied to a DC-DC converting circuit below 50% even if a transient input signal arrives. CONSTITUTION:An input signal ei from an input signal source 1 is inputted to the preamplifier 13 of an output amplifier 2 and a control amplifier 7. The output signal of the control amplifier 7 is applied to an ampliture limiting circuit 40 to clip the peak part of the input signal through the operation of a resistance 41 and Zener diodes 42 and 43 when the signal level exceeds a Zener voltage, i.e. when the input signal ei is excessive, thereby applying the resulting signal to level shifting circuits 8 and 9. Output signals of the level shifting circuits 8 and 9 are applied to voltage comparing circuits 11 and 12, whose output signals are applied to DC-DC converting circuits 5 and 6. Even if the input signal ei becomes excessive, its duty ratio is held below 50% through the ampliture limiter 40, so high frequency transformers 23 and 24 are prevented from getting saturated and switching TRs 25 and 26 never breakdown.

IPC: H01L21/3065
Filed: 1988-01-12
Abstract: PURPOSE:To stabilize the etching characteristics thereby stabilizing the characteristics of a semiconductor wafer by a method wherein the wall of a plasma reaction chamber made of a microwave transmitting material is formed into dual structure with hollow inside to make a heating medium circulate throughout the hollow part. CONSTITUTION:A reaction chamber 2 made of a microwave transmitting material e.g., quartz with the gap between the inner wall 2a and the outer wall 2b specified to be 2-10mm. A gas hardly absorbing the microwaves is used for a heating medium 4 circulating throughout the peripheral wall of the reaction chamber 2 to exchange heat. As soon as the microwaves are led in through the inner wall 2a and the outer wall 2b, a magnetic field is applied to produce a plasma of reactive gas in the reaction chamber 2. This plasma acts on a semiconductor wafer 1 on a holder 8 to bring about the etching effect. The temperature on the wall surface can be controlled by the circulation of the heating medium 4. Through these procedures, the etching characteristics during the plasma etching process can be stabilized to stabilize the characteristics of the semiconductor wafer 1.

Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To easily recognize the category of a program by displaying the program name by means of a font typeface according to the program category. SOLUTION: A program title display object displays the name of a program and shows the program name in a font typeface in response to the category of the program in a program name display area that is sectioned by a program start time and a program end time. That is, a CPU 30 executes the display of an EPG screen by an instruction of a viewer, starts a display processing procedure, reads out the program information data D1 and acquires the category of the program to be displayed. Then the CPU 30 decides a font typeface corresponding to the program category out of the font typefaces which are stored in a ROM 28 based on a category/font correspondence table stored in a RAM 29. The ROM 28 stores five font typefaces, i.e., a special thic Gothic type, a Gothic type, a Ming type, a POP type and a round Gothic type, and the program category corresponds to one of these five types.

IPC: H01L29/78
Filed: 1990-01-12
Abstract: PURPOSE:To prevent the concentration of current and latch-up by providing a source layer around a striped drain layer, wherein the drain-source spacing is greater in the edge portions of the striped drain than in the other portions. CONSTITUTION:An n-type base layer and a drain layer 16 in it are formed in a stripe pattern and divided into three parts. A source layer 13 is formed around the base and drain layers. in this striped area, a relation b>a is determined where (a) and (b) are the drain-source spacing in the linear and edge portions of the stripe pattern, respectively. In this conductivity-modulation MOSFET, the lateral distribution of resistor of the n-type base layer is greater in the edge portions than in the linear portions. Therefore, the distribution of hole current in the n-type base layer is substantially uniform although the source layer 13 faced with the drain layer 16 has longer sides in the edge portions. Thus, the concentration of current in the edge portion is reduced compared with the conventional device.
